To all our customers

Regarding the change of names mentioned in the document, such as Hitachi

Electric and Hitachi XX, to Renesas Technology Corp.

The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas

Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog

and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)

Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand

names are mentioned in the document, these names have in fact all been changed to Renesas

Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and

corporate statement, no changes whatsoever have been made to the contents of the document, and

these changes do not constitute any alteration to the contents of the document itself.

Cautions

Keep safety first in your circuit designs!

1. Renesas Technology Corporation puts the maximum effort into making semiconductor products better

and more reliable, but there is always the possibility that trouble may occur with them. Trouble with

semiconductors may lead to personal injury, fire or property damage.

Remember to give due consideration to safety when making your circuit designs, with appropriate

measures such as (i) placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or

(iii) prevention against any malfunction or mishap.

HD74HC123A

Dual Retriggerable Monostable Multivibrators (with Clear)

ADE-205-438 (Z)

1st. Edition

Sep. 2000

Description

This multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which

can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The

HD74HC123A can be triggered on the positive transition of the clear while A is held low and B is held

high.

The HD74HC123A is retriggerable. That is it may be triggered repeatedly while their outputs are

generating a pulse and the pulse will be extended.

Pulse width stability over a wide range of temperature. The output pulse equation is simply: t_w= (Rext)

(Cext).
